An exit-time approach to -entropy
M. Abel, L. Biferale, M. Cencini +3
An efficient approach to the calculation of the -entropy is proposed. The method is based on the idea of looking at the information content of a string of data, by analyzing the…
Chaotic advection and relative dispersion in a convective flow
G. Boffetta, M. Cencini, S. Espa +1
Lagrangian chaos is experimentally investigated in a convective flow by means of Particle Tracking Velocimetry. The Finite Size Lyapunov Exponent analysis is applied to quantify di…
Non Asymptotic Properties of Transport and Mixing
G. Boffetta, A. Celani, M. Cencini +2
We study relative dispersion of passive scalar in non-ideal cases, i.e. in situations in which asymptotic techniques cannot be applied; typically when the characteristic length sca…
Exit time of turbulent signals: a way to detect the intermediate dissipative range
L. Biferale, M. Cencini, D. Vergni +1
The exit time statistics of experimental turbulent data is analyzed. By looking at the exit-time moments (Inverse Structure Functions) it is possible to have a direct measurement o…
Transport in finite size systems: an exit time approach
P. Castiglione, M. Cencini, A. Vulpiani +1
In the framework of chaotic scattering we analyze passive tracer transport in finite systems. In particular, we study models with open streamlines and a finite number of recirculat…
The predictability problem in systems with an uncertainty in the evolution law
G. Boffetta, A. Celani, M. Cencini +2
The problem of error growth due to the incomplete knowledge of the evolution law which rules the dynamics of a given physical system is addressed. Major interest is devoted to the…
